Different frequency of devices update after migration

qlex3 years ago

Hi,
we're migrating to a new installation of traccar server, as we're moving to a dedicated server.
Config is the same, using latest traccar linux version with mysql config, the previous one is couple months old.
Now, we are gradually updating the devices, by providing new host and port to send gps data to server and comparing the data on web app between traccar deployments.
I noticed that the frequency of updates in the old one was very good and in the new one it is not that frequent, causing the markers to appear sometimes over buildings and not on the road and the vehicles don't move that smoothly.
As there were no changes in the devices and server config, can this be handled somehow ?

Have you checked logs for errors?

Yes i have checked them.
Nothing suspicious, only tries to connect from different devices, so i'm going to allow only certain type.

Logs indicate that data is coming approx. every 10secs, but on webapp it refreshes every 60 seconds only.

I can see also this a lot:

2021-08-16 09:20:23  INFO: [e0fb5eb0: teltonika > 46.134.142.121] HEX: 00000001
2021-08-16 09:20:23  INFO: Position filtered by Distance filters from device: {here comes imei}

Also, I don't know if this is linked, but i observed this strange behaviour too,
when the page refreshes to show current location, the list of devices on the left appears empty, and one must scroll to the bottom of that window to see the devices. Also you can see on the map, how infrequent does the vehicle refresh.

@tananaev
would you have any other suggestions ?

Don't really have any suggestions. If there are no errors in the log, it probably means that it's just what device reports. Not a server issue.

Thanks. the only difference is the traccar version - previously using 4.10 i think and now 4.13.
Same devices, same config - i started newest traccar on new server, reconfiguring devices (switching to new host, same standard 8081 port) and this is the outcome. can there be a difference between those two servers ?

Anything is possible, but the only way to tell for sure is by looking at the logs.
